Title: Micro-ion beam processing method
Inventor: YAMAGUCHI HIROSHI
IPC: H01L21/302
Filed: 1992-06-15
Abstract: PURPOSE:To make even processing feasible on the whole pattern surface by a method wherein the processing requirements for the processing step near the end of a pattern easily processed by sputtering step are differentiated from those for the processing step in the central part of the same hardly processed. CONSTITUTION:When an Al wiring 30 is made on an SiO2 film 29, the intensity of beam current may be increased when the central part of wiring is irradiated with ion beams. Through these procedures, the part near the end easily removed by sputtering step on a pattern side is to be irradiated with low ion beam current while the central part hardly removed is to be irradiated with high ion beam current thereby enabling Al only to be removed evenly. Accordingly, a specimen to be processed with micro-ion beams can mitigate the effect of sputtering step on the sides or the effect of unevenness of material quality thereby enabling a specific processing shape to be taken.

Title: Semiconductor storage device
Inventor: YAMADA TAKASHI
IPC: H01L21/822
Filed: 1989-06-19
Abstract: PURPOSE:To secure the satisfactory capacity of a capacitor even when the occupied area of a memory cell is further reduced by forming a gap between a storage node contact part side wall and a storage node electrode, and employing the storage node electrode part located along the gap part as the capacitor. CONSTITUTION:A gap is formed between a storage node electrode 16 and a storage node contact part 13 side wall, in which gap a plate electrode 18 is formed oppositely to the storage node electrode 16 through a capacitor insulating film 17. Accordingly, it is possible, for the purpose obtaining a capacitor, to use the storage node electrode part 16 located along the inside wall of the storage node contact part 13 that was not used until now as the capacitor. Thus, the surface area of an electrode used as a capacitor is correspondingly increased to result in increased capacity of the capacitor. Hereby, satisfactory capacity can be secured upon reducing the occupied area of a memory cell.

Title: Continuous casting machine of curved type
Inventor: OSADA SHIYUUJI
IPC: B22D11/128
Filed: 1981-10-01
Abstract: PURPOSE:To prevent the generation of a flaw due to a transverse surface crack and a corner crack produced in an ingot by keeping the leveling part for bending of the ingot within specific % of the overall length of a continuous casting machine. CONSTITUTION:In a continuous casting machine of curved type, the leveling part for bending of ingots is kept within 35% of the overall length of the continuous casting machine. More specifically, the rate of solidification of the ingots at the leveling points is kept at <=55% level. Thus threshold strains for generation of cracks can be improved considerably as compared to the case by the prior art and the temp. in the corner parts and surfaces of the ingots can be maintained at temps. other than an embrittling temp. region (700-900 deg.C), for example, at >=1,000 deg.C. Further the releasing of strains is caused by the extremely fast stress relieving resulted from the high temp. region, whereby the generation of transverse surface cracks and corner cracks is obviated.

Title: Apparatus for positional detection of object
Inventor: HAYASHI TAKASHI
IPC: G01B17/00
Filed: 1982-09-06
Abstract: PURPOSE:To prevent error detection caused by an obstacle to enable the accurate and certain positional detection of an obstacle, by detecting the position of the obstacle on the basis of a first and a second distance discriminating signals in cases having a relatively close distance and a remote distance from the obstacle. CONSTITUTION:A first memory oscillator 26 responds to the falling of a reflection signal SG17 to output a pulse signal SG18 to an AND circuit 25. When the AND circuit 25 inputs SG18 at this time, the reflection signal SG17 disappears and, therefore, a first distance discriminating signal SG19 is not outputted. When the reflection signal SG17 based on the next pulse SG13 is outputted after a time T1 from the output of a reflection signal SG14, the first distance discriminating signal SG19 is outputted in response thereto and it is decided that the obstacle is present at a distance relatively close to an unmanned vehicle. Similarly, when SG22 is outputted, it is decided that the obstacle is remotely spaced apart from the unmanned vehicle. As the result, the accurate and certain positional detection of an object to be detected can be performed.

Abstract: PURPOSE:To accurately detect the abnormality of an oxygen sensor by judging the abnormality of the oxygen sensor in such a case that the output signal of the oxygen sensor is equal to or more than a predetermined threshold value or equal to or less than said threshold value when an air/fuel ratio is set to a lean or rich state. CONSTITUTION:The air/fuel ratio of the fuel mixed air supplied to an internal combustion engine M1 is subjected to open loop control by an air/fuel ratio setting means M3 to be set to a lean or rich state. In such a case that the output signal of an oxygen sensor 2 becomes a predetermined threshold value or more when the air/fuel ratio is set to the lean state, it is judged that the sensor M2 is a deteriorated sensor much in an Nox discharge amount. In such a case that the output signal of the sensor 2 becomes the predetermined threshold value or less when the air/fuel ratio is set to the rich state, the sensor 2 is judged to be a deteriorated sensor much in a CO discharge amount. By this method, the abnormality of the sensor 2 can be accurately detected.

Abstract: PURPOSE: To obtain the compact device, by combining a main spool valve and a by- spool valve through a plurality of oil paths, and by continuously working each spool valve in the opposite directions.  
     CONSTITUTION: When driving a pump 10 under the condition shown in the figure, compressed oil enters a chamber 6a to right move a main spool 8. Ports 7f, 7h are communicated, and a piston 3 right works by the difference of the pressure receiving areas. When the main spool 8 shifts only by XL, ports 7b, 7c are communicated, compressed oil flows into a chamber 11a and a by-spool 13 right moves. Thus, compressed oil enters a chamber 6b to left shift the main spool. Consequently, ports 7h, 7g are communicated, and the piston 3 left moves. When the main spool 8 left shifts and ports 7a, 7b are communicated, the by-spool 13 returns to the original location, and compressed oil enters the chamber 6a to right move the main spool 8. The piston 3 is excited by repeating this operation.

IPC: H02P9/30
Filed: 1994-07-07
Abstract: PURPOSE:To provide a controller for a charging generator of a vehicle which can prevent erroneous operation of a charge lamp when a charging generator is operated in an idling state. CONSTITUTION:A controller for charging generator of a vehicle is constituted in such a way that, when the voltage at an L-terminal drops, the base current of a transistor 86 becomes smaller and the voltage across the collector and emitter of the transistor 86 rises so that the set value of a regulated voltage can rise a little and power generation can be restarted, and then, the voltage at the L-terminal can rise. Therefore, when the voltage at the L-terminal starts to drop due to the idling of the engine, the set value of the regulated voltage rises a little and power generation is started and, as a result, the erroneous operation of a charge lamp can be prevented, since the base current of the transistor 86 becomes smaller and the voltage across the collector and emitter of the transistor 86 rises.
